BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of portable optical magnification. More specifically the invention comprises the magnifying glass assembly to be added to an existing watch band, bracelet, belt, purse strap, or any other strap.

2. Problem to be Solved and the Related Art

With age people become farsighted. They need glasses to see close objects. Bifocal glasses are one of the solutions to this problem, however some people do not like to wear glasses. When they are in the store they can see clearly the things they want to buy, however they cannot read the price, or other details. My invention aims to solve this problem by enabling them to just pull out the magnifying glass from its mounting on the watch, belt, or purse strap, stretch it out to the object they want to read the text on, and let it retract back after they are done. It is a much easier and less time consuming process than having to put glasses on and take them off again and again, or search for a magnifying glass in a pocket or purse and remember to put it back.

There are retractable measuring tapes, and retractably mounted objects . For magnification there are several designs of portable magnifying glasses and optical glasses. The prior art U.S. Pat. No. 7,667,903B2, Retractably mounted magnifying glass assembly by Mary Kisko is meant to be connected to a flat surface with stationary frame. The prior art U.S. Pat. No. 5,113,289, Shelf-mounted magnifying glass by Sara Soper, and U.S. Pat. No. 6,441,974 B1 Shopping cart magnifier (E-Z reader), by Thomas A. Miranda, Jonathan C. Roche, Randolph G. Duso have to be implemented by a store owner rather than a customer.

There are also existing patents on a magnifying glass incorporated as a part of a watch case or watch band: U.S. Pat. No. 2,679,785 A, Wrist watch by Hugo Batt where a magnifying glass is a part of a watch case, U.S. Pat. No. 8,125,853 B2 Watch bracelet by Robert Greubel, Stephen Forsey has a magnifying glass as part of the bracelet and U.S. Pat. No. 5,601,222 A Magnifying wristband by Richard Y. Haddad has a magnifying glass built into a watch band.

The present invention differs from previous patents. It is portable, can be just an add-on to the existing watch band, or other strap and no changes to watch or watch band are required. It is easy to make and parts are not expensive.

BRIEF SUMMARY OF THE INVENTION

The present invention comprises a retractable magnifying glass assembly to be slid on a watch band, bracelet, belt, purse strap or any other strap. The assembly has the loop made from rubber, plastic, velcro or similar material that can be slid on, or attached to the watch band. One can extend the magnifying glass from its mounting on the band, and either place it back, or have it automatically retract into resting position after use.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 and FIG. 2 show front and back of the strap 1 with retractable magnifying glass 3 and the spring in one housing 2. The spring and separate compartment for the spring are not depicted. The housing 2 is attached to the strap 1 with a slider 10.

FIG. 2 a is a cross section showing the housing 2 comprising the compartment 21 for the spring containing the spring 4 and compartment 22 containing a magnifying glass 3.

FIG. 3 shows the magnifying glass 3 pulled out from the separate compartment (not depicted) of the housing 2. The magnifying glass is connected to the spring 4 by a cord 5. In its resting position the magnifying glass 3 is adjacent on the flat surface of the compartment of spring 4.

FIG. 4 shows a magnifying glass 3 connected by a cord 5 through a bead 6 to the farther end of the spring 4 allowing for automatic retraction of the magnifying glass 3 into the housing.

FIG. 5 has the magnifying glass 3 connected to the close end of the spring 4 with the spring 4 positioned inline. This configuration also allows for automatic retraction of the magnifying glass 3 into the housing 2.

FIG. 6 shows the version with the retractable spring 4 and a magnifying glass 3 mounted side by side. The spring housing 9 is attached with the slider (not depicted) to the strap. The spring 4 is connected with a cord 5 to the magnifying glass 3. The magnifying glass 3 is connected with a magnet 7 to the spring housing metal extension 8.

FIG. 7 shows a photo of a prototype of the device in use.
